Abstract

This invention relates to agriculture. The aim of the invention is to improve the reliability of the process. When a pressurized water flow is supplied from the irrigation system 10 through the discharge pipe 13 of the sprinkler, a block valve 29 is opened, and water through the throttle 27 and valve 28 enters the hydraulic actuators 5 and 3 of pump 4 and dispenser-pump 2. In case of a sprinkler stop, the pressure in the pressure pipe 13 falls, the block valve 22 closes the drain line 21, and the hydraulic actuator 3 stops. In this case, the pump 4 continues to work and mixes the mother liquor in the tank 1. If the mother liquor is consumed from the tank 1, the float sensor 8 of the level closes the block valve 29, and both hydraulic actuators 5 and 3 stop working, and the block valve 22 is triggered A 24 level signal is given to close the slide valve 14, the water supply is stopped. 1 il.

The invention relates to the field of spruce household, in particular to the irrigation and irrigation machines when introducing chemicals with irrigation water.

The aim of the invention is to improve the reliability of the process.

The drawing shows the hydraulic scheme of the device for introducing the means of chemicalization with irrigation water. A device for depositing chemicals with irrigation water contains a tank 1 for chemicalization solutions, a dosing pump 2 with a hydraulic actuator 3, an additional pump 4 with a hydraulic actuator 5. In the tank 1 there is a hydraulic mixer 6, a filter 7, a sensor 8 level solution, and the pipeline 20 with the crane 9 is connected to the irrigation network 10. The metering pump 2 is hydraulically connected by the suction pipe 11 to the tank 1, and the discharge pipe 12 - c. the discharge pipe 13 of the sprinkler after the hydraulic slider 14, with which the machine is connected to the irrigation network 10. An additional pump 4 is connected by a pipe 15 to the suction pipe 11, into which a three-way filling valve 16 is built in to communicate it to the filling capacity 17. Pressure pipe 18 with a three-way valve 19 integrated in it, it connects the pump 4 to the hydraulic mixer 6. The hydraulic actuators 3 and 5, respectively, of the pumps 2 and 4 by the tube 20 are interconnected. The hydraulic actuator 3 of the pump dispenser 2 by pipeline 21 is hydraulically connected to the discharge pipe of the sprinkler machine 13 after hydraulic valves 14, and through the blocking valve 22 to the drain pipe 23 and through the float sensor 24 level-s with hydraulic protection line 25 sprinkler. The hydraulic actuator 5 of the additional pump 4 is connected via pipe 26 via the throttle 27, the starting valve 28 and the block valve 29 to the hydraulic valve 14 to the irrigation network 10, and pipe 30 to the drain pipe 23. The sensor 8 of the level of solution in the tank 1 is connected to the block valve 31 by pipe 31 29.

The tank 1 refills the mother liquor of the chemicals. The starting valve 28 supplies water to the hydraulic actuator 5 of the additional pump 4. Pump 4

through the filter 7, takes the mother liquor from the tank 1, and through the valve 19 and the pipe 18 pumps it into the tank 1 through the hydro-mixer 6. A process of active mixing of the solution takes place. After some time, by opening the hydraulic slide 14 with the working pressure, the blocking valve 22 is switched to the Open position, which means that the hydraulic drive 3 of the metering pump 2 is put into operation. The pump-dispenser 2 begins to work by supplying 13 doses of the working solution through the pipeline 12 to the discharge pipe of the sprinkler.

When an emergency stop of the sprinkler and the closing of the hydraulic slide 14, the blocking valve 22 is automatically closed, the hydraulic actuator 3 is turned off and the dosing of the stock solution to the discharge pipe 13 of the sprinkler stops, while the process of actively mixing the stock solution does not stop. When the level of the solution in the tank 1 drops, the level sensor 8 by the blocking valve 29 turns off the hydraulic drive 5 of the additional pump 4 and the hydraulic drive 3 of the metering pump 2. The sensor 24 connected through the blocking valve 22 to the drain pipe 23 stops the sprinkler.

The filling of the container 1 is performed in this sequence. The tap 9 is used to fill the water in the tank 1. Starting valve 28 start up the pump 4. When the three-way valve 19 is switched in the Training position and the three-way valve of the filling station 16 is in the position of filling the pump 4, the chemicalization agent is pumped from the filling tank 17 into the container 1. Once the filling is completed, the taps 19 and 16 are again in the working position. After a few minutes of active mixing, the sprinkler is put into operation. Dosing begins only when the sprinkler is filled with water, when the working pressure in the pressure pipe 13 opens the block valve 22.
